Denna rapport har undersökt hur interaktivitet, genom interaktiva barnböcker på mobila enheter med pekskärm, kan påverka engagemanget för läsande hos barn i tre till fem års ålder. Detta har gjorts genom att en interaktiv barnbok skapades och deltagande observationer sedan utfördes vid sex tillfällen på tre förskolor där barnen fick testa den utvecklade produkten. De deltagande observationerna kompletterades sedan med åsikter om digitalt lärande från förskollärare på respektive förskola genom semistrukturerade intervjuer. Resultatet från undersökningen visar på en tendens till att engagemanget hos barnen kan ökas genom att införa interaktivitet i barnböcker genom att leverera dessa på mobila enheter med pekskärm. Undersökningen är dock gjord i för liten skala samt att produkten och undersökningen innehåller för många brister för att kunna ställa upp en faktisk teori. Istället ställs en hypotes upp som skulle behöva testas vidare under längre tid och i en mer rigorös undersökning. / This paper has researched how interactivity, through interactive children’s books on mobile devices with touch screen, can affect the involvement in reading for children in the ages three to five years old. This has been done by creating an interactive children’s book and then conducting participative observations over six occasions at three different preschools where the children got to test the developed product. The observations were then supplemented with opinions on digital learning from preschool teachers from each of the schools through the use of semi-structured interviews. The result from this research shows a tendency that the involvement of the kids can be increased by introducing interactivity to children’s books by the use of mobile devices with touch screen. However the research is at too small a scale and both the product and the research contain too many flaws for an actual theory to be constructed. Instead a hypothesis is constructed that would need to be evaluated during a longer period of time and through more rigorous research.

The object of this project was to develop a device, which would by use to coordinate or control device wireless. The system divided to several independent devices, which assure high comfort for the user. The basic unit contains of touch panel which allow the user to control the system. The second unit is used for communication the system with GSM net. The third unit is used to coordinate the system from a PC. This unit makes possible data collection and their evaluation. This unit can as well control and coordinate any devises in the system. Part and parcel of this system are units which are used to drive the end consumers. The hole system is powered from a instead powers supply which is managed from a microprocessor. These devices make it possible, to the system to work without line voltage. The system is designed modular, so in the future it is possible to expand the system of others peripherals.

The result will be fully functional device. It would measure voltage waveforms within the scope from tens mV to tens V with transmission bandwith from direct-current signal up to tens of MHz

This work deals with description of graphic library for a touch screen educational kit with a microcontroller from Freescale. Part of this library is a driver that accelerates gradient rendering and supports reading from video RAM. The library allows inserting images with transparency and their upscaling. Multiple fonts are also supported. Fonts can be upscaled and their weight can be set.

The purpose of this work was to find what User Interface adjustments are most suitable for elderly users from the age of 60. The adjustments looked upon in this research were regarding three areas: navigation, progress bar and element design. Each area consisted of two characteristics that were compared against each other. Navigation had a slide-out sidebar and top navigation bar as characteristics. While the progress bar and element design had the characteristics of with and without a progress bar as well as icons and detailed images respectively. The research method was to put these characteristics in two prototypes. Then five elderly tested these prototypes as if they were two different prototypes of an application rather than a test of a specific User Interface design. The data were analysed through three aspects for each of the areas: effectiveness (number of errors), efficiency (time efficient) and user satisfaction. The conclusion of the analysis was that the top navigation bar and progress bar were the better User Interface adoptions. While regarding the element design there was not an as clear answer. What was significant was what the image or icon represents is clear, though the elderly user seems to prefer images / Syftet med detta arbete var att hitta de användargränssnittsjusteringar som är lämpligast för äldre användare från 60 års ålder. De inkluderade justeringarna i denna forskning var dessa tre områden: navigering, förloppsindikator och elementdesign. Varje område bestod av två egenskaper som jämfördes jämt emot varandra. Navigation hade ett utdragbar sidofält och övre navigeringsfält som egenskaper. Medan förloppsindikatorn och elementdesignen hade egenskaperna med och utan förloppsindikator respektive ikoner och detaljerade bilder. Forskningsmetoden var att sätta dessa egenskaper i två olika prototyper. Dessa testades sedan av fem äldre som att de vore applikationsprototyper snarare än ett test av ett specifik användargränssnitt. Data analyserades utifrån tre aspekter för var och ett av områdena: effektivitet (antal användningsfel) och verkan (tids effektivitet) och tillfredsställelse. Analysen kom fram till att det översta navigeringsfältet och förloppsfältet var de bättre anpassningarna. Gällande elementdesignen var svaret inte lika klart. Det betydelsefulla där var att det bilden eller ikonen representerar är tydligt för användaren, däremot verkar de äldre användarna föredra bilder över ikoner.

Building upon previous research done on interactivity attributes describing the aesthetic quality of interactions, this paper aims to explore the sense of ow in screen-based interactions, narrowing down to the finer details that make the personality of the interactive experience. The goal is to provide a deeper knowledge on the concrete, expressive qualities of screen based interaction, being “the immaterial material” moulded in the design process. The relevant information for practicing designers is the awareness of what emotions certain interactions elicit and how interactions can be used to convey brand personality.The process conducted followed a research through design methodology, as the aim was to explore the defined design space rather than answer a specific problem. Two major user studies provided insights and refocus in the process along the way to the final result: a set of guidelines and a prototype embodying them. The guidelines provide some details on designing flow experiences on a mobile screen, and are to serve as inspiration and reference to future work and design practice. The prototype, called ‘The Embodiment’ serves as an illustration of the guidelines, as mere words are not able to fully describe the dynamic quality.

L'objectif principal de ce travail de thèse est de discuter de la place de la tablette tactile dans un dispositif d'enseignement adapté et ciblé auprès d'enfants détectés à risque de difficultés ultérieures en lecture. Pour répondre à cet objectif et après avoir étayé notre propos avec les résultats de la littérature scientifique, deux axes sont présentés. Un axe expérimental, composé de trois études, nous a permis de mesurer l’impact d’un entrainement spécifique intensif et individuel, via la tablette tactile, sur les performances en identification de mots écrits d’élèves de GSM et de CP faibles (pré)lecteurs. Plus précisément, les résultats du suivi longitudinal des élèves susmentionnés à court et moyen termes semblent aller en faveur d’une amélioration de la conscience phonologique et du traitement grapho-syllabique. Le second axe s’attachait à mettre en lumière l’importance des critères ergonomiques de développement de deux applications ludo-éducatives. Les résultats des évaluations subjectives permettent d’identifier les points nécessitant un travail supplémentaire, ces points pouvant entraver le traitement d’informations cruciales pour l’apprentissage de la lecture. / The main objective of this thesis work is to discuss the place of the touch-screen tablet in an adapted and targeted teaching system with children detected at risk of subsequent difficulties in reading. To meet this objective, we have presented two main axes, based on the results of the scientific literature. An experimental axis, made up of three studies, allowed us to measure the impact of a specific intensive and individual training, via the touch-screen tablet, on the performances in written words identification of poor (pre)readers in Kindergarten and First Grade. More precisely, the results of the longitudinal follow-up of the aforementioned students seem to be in favor of an improvement of the phonological awareness and the grapho-syllabic treatment. The second axis aims to highlight the importance of ergonomic criteria for the development of two edutainment apps. The results of the subjective evaluations identify points that requiring additional work, which may hinder the processing of crucial information for the learning of reading.

The quality attribute concerning usability is generally of significant importance to systems. The area of Human Computer Interaction, HCI, especially handles several usability aspects. This degree project emphasizes HCI in a context of, so called, Smart House. The report is divided into three main sections: theory, application, and measurement results. In the theory section we will present about the context of HCI and the content of HCI, such as HCI model and goals of HCI design. In the application section we discuss the use of mobile phones as a device to remotely control devices of smart houses, and present a system developed to support such services. In order to make the system more attractive, we decided to design it for two categories of operations, menu operation and direct-touch operation mode. Finally, we have used questionnaires for reasons of measuring user satisfaction. Through investigation and analysis of the result of this, we come to the conclusion that system usability is good.

Un grand défi actuel consiste à réaliser des capteurs innovants tirant partie des propriétés singulières de nanoparticules colloïdales synthétisées par voie chimique et assemblées de manière contrôlée sur des surfaces. L’objet de cette thèse est le développement de jauges de contrainte résistives à base de nanoparticules. Ces jauges de contrainte sont constituées de lignes parallèles, de quelques micromètres de large, denses, de nanoparticules colloïdales d’or synthétisées par voie chimique et assemblées sur des substrats souples par assemblage convectif contrôlé. Le principe de ces capteurs résistifs repose sur la conduction tunnel entre les nanoparticules qui varie de manière exponentielle lorsque que l’assemblée est déformée. Des mesures électro-mécaniques couplées à des observations en microscopie électronique à balayage et à force atomique ont permis d’identifier, de quantifier et de comprendre l’impact de la taille et de la nature des ligands des nanoparticules sur la sensibilité et les phénomènes de dérive de la résistance à vide des jauges de contrainte. Ces travaux, associés à des mesures de diffusion de rayons X aux petits angles ont permis de corréler les variations macroscopiques de résistance électrique des jauges de contrainte aux déplacements relatifs des nanoparticules. Finalement, ces jauges de contrainte ultra-sensibles et miniatures, mises en matrices, ont été exploitées pour réaliser des surfaces tactiles souples multi-points et sensibles à l’intensité de l’appui / One recent big challenge is to implement innovative sensors that take advantage of the unique properties of colloidal nanoparticles chemically synthesized and assembled on various surfaces. The goal of this work is the development of nanoparticle based resistive strain gauges. These strain gauges are constructed of few micrometers wide parallel wires of close packed colloidal gold nanoparticles, chemically synthesized, and assembled on flexible substrates by convective self assembly. The principle of these resistive sensors is based on the tunnel conduction between the adjacent nanoparticles which varies exponentially as the assembly is stretched. Electro-mechanical measurements coupled with scanning electron microscopy and atomic force microscopy observations were used to identify, quantify and understand the impact of the nanoparticle size and the nature of the protecting ligands, on the gauge sensitivity and the drift of the resistance at rest of the nanoparticle based strain gauges. Coupled with small angle x-ray scattering measurements, these studies allowed us to correlate the macroscopic changes in electrical resistance of the strain gauges to the relative displacement of the nanoparticles at the nanoscale. Finally, a matrix of these miniature ultra-sensitive gauges was used to construct flexible touch screen panels capable of measuring the intensity of several touches simultaneously
